How to Repair a Split Bamboo Rod

Bamboo is strong and flexible.

Bamboo's strength and flexibility makes it ideal for many building projects. A cut length of bamboo, called a rod, is strongest when it is whole and unbroken. A split in a bamboo rod reduces its strength. Bamboo rods may split as they age, leaving you to decide whether you should discard or repair the rod. You can fix a split bamboo rod with two-part epoxy and a binding. This process will restore the strength of the bamboo rod and allow you to use it for your project.

Things You'll Need

• Two-part epoxy in an injection applicator
• Razor knife
• Flat screwdriver
• Waxed, rawhide twine
• Spray polyurethane
• Rubber gloves
• Safety glasses
• Dust mask

Instructions

1. Remove the cap from the tip of your injection applicator. Cut off the tip of the applicator with your razor knife so that the epoxy is ready for use.

2. Push the tip of your flat screwdriver into the split in the bamboo rod. Twist the handle of the screwdriver to open the split. Have your assistant hold the screwdriver and rod in this position so you'll have easy access.

3. Slide the tip of your injection applicator into the split. Press the plunger on the applicator to fill the inside of the bamboo with epoxy.

4. Twist the handle of the screwdriver to let the split close. Pull the screwdriver free. Wrap waxed, rawhide twine around the bamboo rod repeatedly to cover the split. Tie the ends of the twine together in a double knot and trim the excess twine with your knife.

5. Spray polyurethane onto the twine. Leave the rod on a flat, dry surface to let the polyurethane and epoxy dry completely before you use the bamboo rod.

Tips & Warnings

• Rubber gloves, safety glasses and a dust mask are required when using epoxy, polyurethane and other chemical compounds.

• Work outside or in a well ventilated, indoor space when using chemicals.
